I am trying to see if anyone can help me identify a component on a PCB. This device took a voltage spike on its AC line from a lightning strike on our home, and the unit is no longer working.
The component is labeled "SA1" on the PCB, but as you can see, only half of the device remains so I can't get enough unique numbers to cross reference anywhere. This board is immediately down-stream from the power on/off switch, and if I am following the traces on the PCB correctly, this component is soldered between the neutral and ground planes; the hot side of the 120vAC feed is fused with a 5A-250V fuse.
The failed component almost looks like it was a halogen style bulb, but not sure why there would be one in this location on the system, or how it would work with placement between ground and neutral, unless the yellow wire is actually the hot and black is neutral which seems counter to typical color coding practice.
The PCB is labeled with "E154554" & "SH-A 94V-0", but searches for that show many different PCBs with none looking anything like this board. I even saw those same numbers on other boards in this device, so that was rather weird and explains why I am not finding anything in my searches.
If you have any guidance, I would really appreciate it. Just trying to see if replacing this part will fix the issue, or if the spike was such that it has fried things all over inside this unit.
